Background
In order to protect the environment nowadays, along with the improvement of the environmental protection requirement, more and more transformer substations are classified into class ii standards, and the corresponding standard limit values of the environmental noise of the factory boundary are as follows: the daytime is less than or equal to 60dB (A), and the nighttime is less than or equal to 50dB (A), a consensus is formed for transformer substations, main sound source equipment of the transformer substations is main transformer and high-resistance, under the condition that the noise reduction technology of an equipment body is immature, an auxiliary noise reduction measure represented by a sound barrier is still the most direct and effective method, the sound insulation barrier is widely used for the transformer substations at present, the noise reduction effect is obvious, and the following problems exist: the installation of the sound insulation barrier 1 causes certain inconvenience to the operation and maintenance of part of equipment, and the sound insulation barrier at the position of the part 2 is set to be too high, so that the sound insulation barrier is not attractive and is not economical.
SUMMERY OF THE UTILITY MODEL
To prior art not enough, the utility model provides a inhale sound insulation and prevent hot wall for transformer substation for replace the current hot wall that prevents, improve greatly and prevent the sound insulation performance of inhaling of hot wall, reduce the diffusion of transformer and highly resistant noise toward factory boundary, thereby effectively reduce the sound insulation barrier height of enclosure department.
The utility model adopts the technical proposal that:
a sound absorption and insulation firewall for a transformer substation comprises a reinforced concrete strip foundation, reinforced concrete stand columns, reinforced concrete beams, a bubble concrete sound absorption wall and a solid sound insulation wall; the reinforced concrete strip foundation is buried below the ground surface, a plurality of reinforced concrete stand columns are vertically arranged on the reinforced concrete strip foundation at equal intervals, the reinforced concrete stand columns are fixedly connected with the reinforced concrete strip foundation, a plurality of reinforced concrete beams are arranged among the reinforced concrete stand columns in parallel, the reinforced concrete beams are fixedly connected with the reinforced concrete stand columns, and the reinforced concrete beams, the reinforced concrete strip foundation and the reinforced concrete stand columns form a plurality of stress frames; one side in the atress frame has been laid brick solid sound-proof wall, and the opposite side has been laid the bubble concrete and has been inhaled the sound wall, is equipped with the sound insulation air bed between solid sound-proof wall and the bubble concrete sound-proof wall.
The reinforced concrete strip foundation is a T-shaped section.
The horizontal distance between the reinforced concrete upright columns is less than or equal to 4 meters; the vertical distance between the reinforced concrete beams is less than or equal to 4 m.
The utility model has the advantages that:
1. the utility model discloses can not increase the transformer substation and prevent hot wall overall dimension and construction cost, do not influence the fortune dimension of other equipment, compare with ordinary hot wall and have better sound insulation performance of inhaling to pleasing to the eye, economy.
2. Utility model's durability is good, and is long in life cycle, can extensively use in transformer substation's noise control.

Detailed Description
The technical solutions in the embodiments of the present invention will be described, clearly and completely, and the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, in the accompanying drawings of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model relates to a sound insulation enclosure for transformer substation, including reinforced concrete bar form basis 1, reinforced concrete stand 2, reinforced concrete roof beam 3, bubble concrete sound absorbing wall 5, entity sound insulating wall 4 and sound insulation air bed 6.
Reinforced concrete bar foundation 1 buries below the earth's surface, and reinforced concrete bar foundation 1 is preferred T shape cross-section for reinforced concrete bar foundation 1 is more stable. Equidistantly vertically arranging a plurality of reinforced concrete stand columns 2 on the reinforced concrete strip foundation 1, fixedly connecting the reinforced concrete stand columns 2 with the reinforced concrete strip foundation 1, parallelly arranging a plurality of reinforced concrete beams 3 between the reinforced concrete stand columns 2, fixedly connecting the reinforced concrete beams 3 with the reinforced concrete stand columns 2, and forming a plurality of stress frames by the reinforced concrete beams 3, the reinforced concrete strip foundation 1 and the reinforced concrete stand columns 2. A solid sound insulation wall 4 is bricked on one side in the stress frame, and the solid sound insulation wall 4 can be made of concrete or bricks, so that the sound insulation wall has a fireproof effect; and a bubble concrete sound-absorbing wall 5 is laid on the other side of the stress frame, and a sound insulation air layer 6 is arranged between the solid sound-insulating wall 4 and the bubble concrete sound-absorbing wall 5.
During construction, the reinforced concrete strip foundation 1 is pre-buried below the earth surface, the reinforced concrete columns and the reinforced concrete beams 3 are poured at certain intervals to form a stress frame, then the solid sound-insulating wall 4 is bricked on one side in the stress frame, the bubble concrete sound-absorbing wall 5 is laid on the other side in the stress frame, the bubble concrete sound-absorbing wall 5 is located on one side close to a sound source, the solid sound-insulating wall 4 is located on one side far away from the sound source, the solid sound-insulating wall 4 and the bubble concrete sound-absorbing wall 5 are tightly attached to the stress frame, and a sound-insulating air layer 6 is formed between the bricked solid sound-insulating wall 4 and the bubble concrete sound-absorbing wall 5. When the transformer substation produces the noise, the noise sound wave is at first through bubble concrete sound absorbing wall 5, and the bubble hole in bubble concrete sound absorbing wall 5 is at first absorbed the noise sound wave, and when the noise sound wave was too big, the noise sound wave passed and enters sound insulation air bed 6 behind bubble concrete sound absorbing wall 5 to carry out the sound wave bounce-back after touching entity sound insulation wall 4, the noise sound wave of bounce-back is absorbed by 5 secondary of bubble concrete sound absorbing wall, carries out the sound insulation with this principle.
